Amazon, Microsoft, and Google are converging on the same enterprise agent architecture

The New Stack · 16 hours ago

Amazon, Microsoft, and Google have each launched enterprise agent platforms that converge on the same core architecture including runtime, memory, tool gateway, identity, observability, and governance components. AgentCore reached general availability in October 2025, Microsoft Foundry launched January 1 2026, and Google's Gemini Enterprise Agent Platform launched at Cloud Next 2026. The lack of a vendor-neutral contract means enterprises currently cannot easily move agents between cloud providers without rebuilding, similar to the fragmentation that existed before Platform-as-a-Service standards emerged in 2011-2016.
